You don't have to play deadly every game but if you play shite you deserve to get took off unless your uncle Mickey is the manager.
Did Mickey Harte ever take Sean Cavanagh off if he was having a bad game?
Does he ever take Mattie Donnelly off if he's having a bad game?
Would he take Cathal McShane off anymore if he's having a bad game?
You generally keep your most dangerous and influential players on the pitch.
Harte was having a pretty indifferent AI semi final against Monaghan in 2018 but came to life in the last 15 minutes and was influential is us winning that match. That's what he is capable of and we have very few players as talented and capable as he is.
